Spoilers

Premise

The story takes place in 2045, a future in which advances in artificial intelligence have made space travel accessible to anyone, and the space station has both internet access and a convenience store.³ Two children born on the moon, Touya Sagami and his childhood friend Konoha B Nanase, are undergoing rehabilitation at the Japanese-built station Anshin to prepare for migration to Earth. Three children from Earth, Taiyo Tsukuba, Miina Misasa, and Hiroshi Tanegashima, arrive on their first space trip, and the five are caught in a collision accident between the station and a comet.³^•⁶

Separated from the adults and cut off from the network and oxygen supply, the children work to escape the station on their own, contending with depressurization, extravehicular activity, and runaway micromachines.³ As the crisis deepens, they learn that a commercial comet is scattering debris toward Earth and Anshin as part of a plan by Seven, an artificial intelligence that was supposed to have been disposed of, and that the children themselves have been designated attack targets by UN2.1, which fears Seven's revival.³ Touya gradually comes to understand the true meaning of a terrible prophecy issued by Seven, described as the most intelligent AI in human history and the creator of the implants inside Touya's and Konoha's brains.⁷

Production

Mitsuo Iso, known for Den-noh Coil, had not directed a series since that 2007 television anime; The Orbital Children was his first directorial work in roughly 15 years, and the studio Production +h. was newly established for its production.¹ Iso handles original story, screenplay, and direction, with character design by Kenichi Yoshida and Toshihiko Inoue, who had worked on Den-noh Coil and Ghost in the Shell, as main animator.⁵^•¹ The voice cast includes Natsumi Fujiwara as Touya Sagami, Azumi Waki as Konoha B Nanase, Kensho Ono as Taiyo Tsukuba, Chinatsu Akasaki as Miina Misasa, Yumiko Kobayashi as Hiroshi Tanegashima, and Mariya Ise as Nasa Houston.⁵

The series was distributed in an unusual combination of formats: all six episodes streamed simultaneously worldwide on Netflix, while in Japan the episodes were grouped into two theatrical films, Part I "Messenger from Earth" (episodes 1 to 3) and Part II "A Story Begins" (episodes 4 to 6), each given a two-week limited cinema run, with Blu-ray and DVD sold in theaters at the same time.¹^•⁴

Astronaut Soichi Noguchi, the fifth Japanese astronaut in space and holder of a record for flying on three kinds of spacecraft (the Space Shuttle, Soyuz, and Crew Dragon), took part in a published conversation with Iso; a remark by Noguchi was one of the triggers for the project, and Noguchi described the work as a story that portrays space expansion favorably.⁴

Reception

Critical response was divided. The review aggregator Rotten Tomatoes recorded a 62% Tomatometer score for the season based on four reviews.⁸ The South China Morning Post gave the series two stars out of five, praising the detailed animation while criticizing heavy technobabble and limited character development.⁹ Other reviewers were more favorable: Slashfilm called it a dense science fiction adventure covering wide thematic territory, and Anime Corner wrote that it revived a lost love for space anime.¹⁰^•¹¹ On Douban the series holds a 7.6 rating from about 1,800 users, and on the Japanese service Filmarks it averages 3.8 of 5 from more than 3,500 reviews.¹²^•¹³

The series' reputation grew after its initial release. Its first terrestrial television broadcast began on NHK General on November 11, 2023, and Japanese commentary at the time of that broadcast described the work as highly regarded for its completeness.³^•¹⁴ A comic adaptation began serialization on the web version of Young Jump on May 12, 2023.³

Themes and science fiction approach

The series presents space in 2045 as an ordinary, commercialized environment rather than a hostile frontier, and its tagline is "You cannot escape from the future."³ The Science Fiction Encyclopedia describes it as an impressive, densely packed series with strong animation and careful worldbuilding, covering themes including whether children's education should be filtered, whether "the greater good" can justify terrible deeds, and whether self-sacrifice for a cause is admirable; in its ending, the children's livestreamed story inspires an estimated 36.79% of the population to emigrate off planet within 50 years.¹⁵
